Hello @pua0609, I shared a document in another discussion that lists the supplements in the protocol along with links to the specific research related to how they help with neuropathy - https://connect.mayoclinic.org/comment/957496/. It's no longer called the Protocol 525 which actually stood for 5 capsules in the morning, 2 at noon and 5 in the evening. Now they have combined some of the supplements into fewer capsules so we only take 4 morning, 2 noon and 4 evening. They have a frequently asked questions page on their site here - https://theprotocolworks.com/faq//
